Obama will attend memorial service in Arizona

President Barack Obama will fly to Tucson, Ariz., on Wednesday for a memorial to commemorate the victims of Saturday’s shooting, a senior administration official confirmed Monday.

Obama has responded swiftly — and publicly — to the shooting that left six dead, Rep. Gabrielle Giffords (D-Ariz.) in critical condition and 13 others injured. The White House has been issuing regular updates on Obama’s briefings with security officials, in addition to identifying lawmakers and victims’ relatives he has contacted.
